The pressure of an ideal gas versus the number of moles at constant temperature and volume. Which graph represents the plot?
E) none of these

Question

Quizplus · Accepted Answer

According to the Ideal Gas Law, PV = nRT, if temperature and volume are kept constant, then PV = constant. This means that as the number of moles of gas increases, the pressure will decrease. The graph in option B shows a decreasing trend of pressure with an increasing number of moles, while the other graphs show either constant or increasing pressure with an increasing number of moles.
